PUMP.

SPECIFICATION. forming part of Letters Patent No. 274,965, dated April 3, 1883.

A pplication filed June 2l, 1882; (No model.)

To all whom it may concern Beit known that I, LEWIS Parme, a citizen ot the United States, residing at Springtield, in the'county otl Clarke and State of Ohio, have invented certain new and useful Improvements in Pumps; and l do declare the following to be a f'nll, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accomlvianying drawings, and to the letters and figures ot' reference marked thereon, which form a part otl this specification.

My invention relates to that class of iron pumps which operate both by force and by suction.

`The objects of my invention are, first, to keep up a continuous tlow of water from the discharge-spout; second, to produce a pump which is simple in construction and easilyand cheaply made; third, Vwhich is durable and strong in its working parts; fourth, having the cylinder in which the piston works cast in such a form as to be bored out in less time and with. much less expense than is done in ordinary iron-pump cylinders; "iitth, having the piston-packing made adjustable by a sirnple device which shall keep it tight and in complete working order; sixth, having the lower valve-box made to lock into place and readily unlockedand removed when required; seventh, having thoeduction-valve made with a simple device for 'arresting its lii't at the proper point and for allowing` a continuous ilow of the' Water through the valvechamber when it is raised to the stop-point; eighth, having the base of the pump, inclosing the rod and the stem, made so that the working parts of thepumpcan be easily taken ont through the same, and to allow ot' the inspection of those parts belowthe platform when required; ninth, bracing the pump and its connections by a peculiar arrangement to prevent the same from being loosened by operating it.

i 4Figure l is an elevation of my improved iron pump. Fig. 2 is an enlarged view of the "same without the base, which is shown in Fig. 5. Fig. 3 is a longitudinal section of the operative parts ot' the pump below the platform. Figs; 4, G, 7, 8, 9 are details; Fig. 10, an enlarged view ot' the cylinder and the parts contained therein.

Ais thepump, which consists ofthe pipe d, having an air-chamber, c, at the upper end, above the discharge-spout, over which is fulcrumed the handle d', to the end ot' which a gas-pipe pump-rod, a., is connected by a pin, l, passingthrongh it. The end of the pipe-rod above the pin is threaded inside 'orthe setscrew c, which secures the pin therein and allows the rod to be easily and quickly detached,

vso that it can be `withdrawn from the pumpcylinder b, which is shown below the platform P of the well in Fig. l, and in the longitudinal section, Fig. 3. The cylinder b is cast in one piece, with the curved eduction-pipeleading from its interior, and the globular valvechamber e on it. The stalk-pipe or stem d passes down through the base B, (sce Figs. l, 5, and 6,) and is screwed into the valvechamber c until its end reaches theinterior The cylinder b is cast with the circular ribs o' and 0" on the inside, as seen in-Fig. 3, the object of which is to save time in boring out the cylinder to lit ihebrass tubular lining L, inserted therein. The boring takes place after the cylinder is cast and before the lining `is inserted. It will only be necessary to smooth the ribs. By casting the ribs with the cylinder the necessity ot' boring out the whole inner surface is obviated, which boring would require seven or eight times the labor of simply smoothing the ribs that sustain the cylinder-lining in place equally as well asit' the whole inner' surface ot' the cylinder were entire. The object of thevribs is to save metal and labor and cost of manufacture', whereas it' the ribs were not cast with the cylinder it would be necessary to cut out about seven-eighths of the metal to form them.` In the `ligure referred to two ot' these rings are seenone at thetop and one near the bottom ot the cylinder opposite the eductioii-pipe-ior the purpose ot' supporting tlie'lining away from the cylinder. The two are connected by a vertical rib, c", which is also ont with the boring-tool to the saine gage with the rings c', and is intended to snpport the seam in the brass lining l, which is driven tightly down into the cylinder until it reaches its seat on a rib, 0', which is cast on the inside, but not bored out, this being as far down as the throw of the piston extends.

The valve-box O is slightly less in diameter than the lining Z, and sets in the bottom ot' the cylinder, where it is secured by a wire latch, s, the end ot' which is sprung out into ICO IOS

the circular recess a under the rib 0"', as seen in Fig. 3. The valve-box C in Fig. 7 is seen from the under side, with the valve shown in dotted lines. It will be seen that the wire latch s is coiled at one cud around a button, K', cast on the inner depressed segment, p, of the box, its end extending from this through a notch, a', in the side of the valve-box. It eX-' tends almost diametrically across the threaded taper hole u in the segment p, the object being to allow it to be unlocked from out the groove n. (See Figs. 7, S, and 9.)v This is done by inserting a rod having a taper screw into the hole, which, as it is screwed in, pushes aside the wire and unlocks it.

In Fig. 9 the operation is illustrated. The rod 6 (a broken section of which is shown) is screwed down through hole u in the segment. As it reaches the bottom of the hole it comes in contact with the wire s, which it pushes to one side, thusdisengagingits end from groove a under rib 0', releasing the valve-box, which can then be easily drawn out with the rod.v The depression in the top of segment p, being somewhat conical and terminating in the hole u, guides the end of the rod to the hole, so that it may be readily inserted. The cylinder is smaller in diameter at the lower end, where the valve-box rests. By the arrangement described a renewal of the valve can be easily made without the necessity ot' drawing out the pump. The valve t in the eduction-pipe, havingits seat in the bottom of chamber c', has a spherical end, with a belt forming a shoulder on which it rests. It has a long thin upright stem, which is of nearly the same width as the caliber of the stem d, in which it fits loosely. It is grooved on either side, the groove beginning near the edge ofthe shoulder and extending throughout its length, the object of which is to allow the water to pass by it upward when it is raised to its full height. A projecting stop,j', on each side, in line with the edge of the stem, just above the head, arrests the motion of the valve at the proper point. This stop strikes the lower end of the pipe d, which extends down into the top of the valve-chamber for that purpose. The hole tapped in the latter for the pipe is large enough to allow the valve to be dropped through it onto its seat. After it is inserted the end of the pipe is slipped down over its stem and screwed into its place.

vThe packing of piston D is made so as to be easily and quickly expanded to the surface of the cylinder by simple means, which will be hereinafter described. Its rod a is of gas-pipe, with a solid end, t', ou which a coarse-threaded screw is first cut, upon which a cast conical nut, u', is fitted, which forms the expander. Below this part the rod is smaller, and a finer screw-thread is cut thereon. After screwing on the conical nut to its place a washer, fw', is slipped on the end of the rod, over the smaller part, and next to it a leather cup, pressed out from a single piece of sole-leather, which forms the outer packing next the cylinder-lining.

This cup has -within it an elastic ring, t", of rubber or other equivalent material,into which the conical expanding-nut u'extends. Under the leather cup a washer-nut, a", is screwed upon the rod, tightening the inside washer, fw, up against the shoulder formed by the end of the coarsly-threaded part traversed by the expander. This completes the piston. When it is necessary to tighten the packing all that is required is to give the expander a slight turn downward, when it is forced into the elastic ring r', expanding it and the leather packing 1.', next the lining of the chamber. This is done without removing any part ofthe piston from the rod and without the use of tools of any kind.

The base B, which incloscs the stalk d and the rod a of the pump, is elevated somewhat above the platform P, and has a main chamber for the stalk d, and a smaller one extending` from and opening into the other for the rod. This latter is provided with a hinged lid, a', to allow the pump-rod audits piston I) to be withdrawn from the cylinder through it without disturbing the other parts of the pump. To secure the pump firmly in its position above theplatform abrace-rod, 2,of triangular shape, having its two ends riveted in the opposite ends of a atbar, 3, is used. Its upper angle is looped over an upper cut notch, o, on one side of the stalk, near the spout, (see Figs. l and, 2) where it is fastened by a machine-screw tapped in above it, with a washer under its head overlapping the-rod. The bar 3, which forms the foot-piece, is screwed down upon the platform, and a brace, 4, extending from an ear on the cylinder up to the middle of the footpiece 3, into which it is screwed, forms the bracing below the platform. These braces stand at an angle with the pump-stalk and sel cure it very iirmly to the platform, and when necessary to remove the pump from the well are easily and quickly detached.

A small hole, o', is made in the top of the air-chamber e to allow it to partially till with water, and thus facilitate acontinuous flow from the discharge-spout as the pump is operated.
